Thank you for purchasing the E-flite™Apex™selectable rate DC Peak Prediction
charger.This charger is DC-powered and will peak charge 6/7-cell Ni-Cd and Ni-MH
slow flyer battery packs.You can choose to charge your battery pack at 400mA,
750mA or 1.5 amps.This charger's unique peak prediction circuitr y ensures that
your batteries receive an accurate charge ever y time and protects your Ni-Cd and
Ni-MH batteries from the dangers of over charging.Your charger does this by
continuously monitoring the battery's voltage charge curve and calculates (predicts)
when the peak (100% charge) will occur.When the batteries have peaked, it stops
fast charging at exactly that point.This is essential in order to avoid damaging Ni-Cd
and especially Ni-MH cells that are very sensitive to heat.This circuitr y is super ior to
conventional peak detection circuitry which continues to fast charge even after the
batteries are fully charged, which may cause damage to Ni-Cd and Ni-MH cells.
After the battery pack has peaked, the charger automatically switches to Advanced
Trickle Charge.This charging process keeps your battery packs in top performing
condition until you are ready to use them.

Your charger will have to be powered by connecting it to a 12V power source,
such as a 12V Sealed Battery (HAN102) or automobile battery.If you choose to
power your charger by connecting it to your automobile batter y, ne
ver do so with
the vehicle running!
DC Power
Attach the red (positive) alligator clip or banana plug to the red (positive) terminal on
your 12V power source.Next, attach the black (negative) alligator clip or banana plug
to the black (negative) terminal of the power source. When this is successfully done, a
"beep" will sound and the LED will illuminate.
Charging 6- or 7-cell Sub-C Ni-Cd or Ni-MH Battery Packs
1. Connect the charger to the 12V power source.
2. Select the charge rate for charging your battery pack.
3. Connect the charge lead of the charger to the connector of the batter y pack.
Note: After you have properly connected the battery to the charger, a "beep" will
occur and the LED will illuminate solid red.
Selectable Charge Rates
The following are estimated charge times based on fully discharged battery packs.Be certain
that you monitor your battery pack while it is being charged.
400mA charge rate
110mAh battery pack 15 minutes
270mAh battery pack 40 minutes
750mA charge rate
270mAh battery pack 20 minutes
350mAh battery pack 28 minutes
1500mA (1.5 amps) charge rate
600mAh battery pack 24 minutes
900mAh battery pack 36 minutes
After your battery pack has peaked, your charger will automatically switch to Advance
Trickle Charge.This feature will keep your battery pack fully charged until you are
ready to use them again.You will know that your charger is in Advanced Trickle Charge
when your charger beeps repeatedly and the LED continually flashes.
To re-peak your battery pack, disconnect the battery and then re-connect it. This
will begin the charge process again. Once the batter y has once again peaked, the
charger will return to Advanced Tr ickle Charge.
Do not leave the battery and charger unattended while in use.When charging, constantly monitor the temperature of the battery pack. If the batter y becomes hot to the
touch, discontinue the charging operation immediately by disconnecting the battery
pack. Do not allow children to charge battery packs unless they are supervised by a
responsible adult.The charger can become hot dur ing charging, so use care when
selecting where you will charge the battery packs.
